The iRobot Braava 320 was originally released in 2010 as the Mint (model number: 4200) by Evolution Robotics. In 2012, however, iRobot took over Evolution Robotics and in 2013 the name was changed from Mint to Braava. The iRobot Braava 320 has an all-white body with black edges, marked with iRobot Braava on the top left corner. The earlier models, Evolution Robotics’ Mint, look identical but have mint printed on the right corner of the lower deck. This is not to be confused with iRobot's more advanced model, the Braava 380t, which features an all-black body.

The Braava 320 is part of iRobot’s home cleaning robot lineup capable of sweeping and mopping. Once paired with the included NorthStar Navigation System and powered on, the Braava 320 begins mapping the room by marking obstacles, walls, and drop-offs. With each cleaning cycle, the Braava becomes more efficient with the path it takes. While in sweep mode it can cover up to 800 square feet, but is reduced to 250 square feet while mopping to focus on a smaller area before the cloth becomes dry. In either cleaning mode, you can use a disposable cloth or a reusable microfiber cloth.
